WASHINGTON (CNN) - President Bush on Thursday slammed last week's advertisement from an anti-war group that criticized the top military commander in Iraq and upbraided Democrats, saying they were skittish about criticizing the group.

Bush, at a press conference at the White House, was asked about his reaction to MoveOn.org's ad in The New York Times that "mocked" Gen. David Petraeus as Gen. "Betray Us."

The president called the advertisement "disgusting." The group and other war critics have accused Petraeus and the Bush administration of "cherry-picking" to make it seem that military success is being achieved in Iraq.

Petraeus and U.S. Ambassador to Iraq Ryan Crocker, in reports to Congress last week, said they believe the U.S. troop increase, or "surge," has had successes, an assertion questioned by war critics.

A general, in the position that Petraeus is in, should be fully capable of presenting facts to the American people. I'm not sure who prompted him to distort the numbers (hello Bush, is there anyone at home?) but he did, and he must have been fully aware that he did. If he was not aware of the distortion of facts, then he isn't qualified for the job. Thank-you MoveOn for staying on top of all of this. I think most people are so sick of the war, so sick of the lies and so sick of the loss of life and casualties.
